Frigidaire dishwasher won't drain

dishwasher won’t drain at all. I can hear the pump trying to work and it sounds weird like something is stuck or clogged. But I can’t find anything clogged in the hoses and am unsure where to go from there.

There probably is (what you said)…here is the pump part number [COLOR=#0000ff]Drain pump kit[/COLOR]
Part Number: [COLOR=#0000ff]AP4318633[/COLOR] made by FRIGIDAIRE

is there anything else to try before buying a replacement part?

Not really the impellar in those pumps strips out easy especially if it’s noisy
